Method and apparatus for sealing french doors for a freezer compartment

ABSTRACT

An appliance having at least a freezer compartment. The appliance may include a pair of freezer doors accessing the freezer compartment. The freezer compartment may include one or more freezer shelves. A mullion may include a movable portion and a fixed portion for sealing the pair of freezer doors.

BACKGROUND

The present embodiments relate to a method and apparatus for sealing French doors for a freezer compartment integrated into an appliance.

Typical French doors for use on a freezer include a vertical case between two freezer compartments to seal the French doors, thereby creating a left and right side freezer compartment. The remaining case completely surrounds each freezer compartment. However, this practice when French doors are used on the freezer compartment reduces the size (e.g. width) of each freezer compartment, meaning a single freezer compartment (e.g. left or right) does not extend fully across the appliance. Moreover, the internal freezer shelves are correspondingly sized to the individual, left or right, freezer compartment (e.g. half width compartment) and do not extend typically beyond the width of a single door, as such they do not extend fully across the width of the appliance. Moreover, if an articulating mullion is attached to one of the freezer doors the price and complexity may adversely increase. Thus, there is a need to seal a full width freezer compartment with French doors and still be able to deploy one or more shelves or bin compartments though the opening allowed by both doors in the open position instead of limiting the width of the freezer shelf.

SUMMARY

In some embodiments of the invention, for example, an appliance having at least a freezer compartment may comprise a housing. Moreover, the housing may include at least a freezer compartment and may define an opening into the freezer compartment. In various embodiments, the appliance may include a pair of freezer doors rotatably attached adjacent the opening into the freezer compartment to the housing, each of the freezer doors may have an open position and a closed position to allow access to the freezer compartment.

DETAILED DESCRIPTION

Numerous variations and modifications will be apparent to one of ordinary skill in the art, as will become apparent from the description below. Therefore, the invention is not limited to the specific implementations discussed herein.

The embodiments discussed hereinafter will focus on the implementation of the hereinafter-described techniques and apparatuses within a residential refrigerator appliance such as refrigerator appliance 10, such as the type that may be used in single-family or multi-family dwellings, or in other similar applications. However, it will be appreciated that the herein-described techniques and apparatuses may also be used in connection with other types of refrigerator appliances in some embodiments. For example, the herein-described techniques may be used in commercial applications in some embodiments. Moreover, the herein-described techniques may be used in connection with various refrigerator appliance configurations. Implementation of the herein-described techniques within refrigerators, bottom freezer refrigerators, top freezer refrigerators, wine refrigerators and beverage centers, compact refrigerators, standing freezers, side by side refrigerator, etc. using French doors would be well within the abilities of one of ordinary skill in the art having the benefit of the instant disclosure, so the embodiments are not limited to the bottom freezer refrigerator implementation discussed further herein. In some embodiments, the appliance or device utilizing the sealing method and apparatus for a cavity or compartment need not be a freezer, or even refrigerated.

Turning now to the drawings, FIG. 1 illustrates an example refrigerator appliance 10 in which the various technologies and techniques described herein may be implemented. Refrigerator appliance 10 is depicted in this example as a four-door or T-type refrigerator, and as such includes front-mounted French doors 12 in a cabinet or housing 14 that provides access to the freezer compartment 13 housed within the cabinet or housing 14. Similarly adjacent pivotable French doors 16 may provide access to the fresh-food compartment 15 and when in the open position (FIG. 1), food and beverage items may be inserted into and removed from the fresh-food compartment 15. French doors 12 are rotatably attached to the housing 14 adjacent the freezer compartment 13 and/or opening 13 a. French doors 12 are generally provided with a hinge 17 along a corresponding side or front edge of the housing 14 adjacent the freezer compartment 13 and is pivotable between a closed position (not shown) and an open position illustrated in FIGS. 1-5. When French doors 12 are in the open position, food and beverage items may be inserted into and removed from the freezer compartment 13 through the French doors 12 or, alternatively, through an opening in the door 12. Moreover, when the French doors 12 are in the open position, one or more compartment bins, baskets, or shelves 20 may be deployed from the freezer compartment 13.

Control over refrigerator appliance 10 by a user is generally managed through a control panel, which can be disposed on a door such as a doors 12, 16. Control panel can also be disposed within the freezer compartment 13 in another embodiment, or in multiple doors, and can be utilized with a user interface for the refrigerator appliance 10. It will be appreciated that in different refrigerator appliance designs, the control panel may include various types of input and/or output devices, including various knobs, buttons, lights, switches, textual and/or graphical displays, touch screens, etc. through which a user may configure one or more settings.

As shown in the Figures, the substantially full width freezer compartment 13 may be subdivided by one or more partitions or mullions 30, 130, 230 adapted to seal the one or more French doors 12. The mullion 30, 130, 230 provides a sealing surface 31 for the receipt of one or more of the French doors 12 (e.g. one or more gaskets). The freezer compartment 13 may extend substantially across the width of the appliance 10 as shown, or alternately may be a variety of sizes (e.g. widths), shapes, quantities, constructions, etc., and still be within the scope of the invention herein. The outer case or housing 14 surrounding the freezer compartment 13 may define an opening 13 a into the freezer compartment. The mullion 30, 130, 230 may intersect the opening 13 a in one or more configurations with a variety of positions/orientations. As shown in FIGS. 1-4, the mullion 30, 130 is substantially vertical and/or aligned centrally within the opening 13 a. In the embodiment shown, the mullion 30, 130 separates the opening 13 a into a pair of openings 13 b, 13 c, with a corresponding French door 12 disposed over a respective opening 13 b, 13 c. In FIG. 5, another configuration of a mullion 230 is shown intersecting the opening 13 a of the freezer compartment 13 creating two different shaped openings 13 b, 13 c.

As shown in the Figures, the refrigerator appliance 10 may include one or more mullions 30, 130, 230 to seal the French doors 12 of the freezer compartment 13. In the embodiments shown in the Figures, the mullion 30, 130, 230 includes one or more movable portions 32 combined with one or more fixed portions 34. The combined movable portion 32 and the fixed portion 34 of the mullion 30, 130, 230 may provide the sealing surface 31 for the gasket of one or more portions of at least one French door 12. The one or more movable portions 32 may be positionable relative to the one or more fixed portions 34 of the mullion 30, 130, 230, freezer compartment 13, freezer compartment opening 13 a, housing 14, and/or shelf 20 between a sealed position (FIGS. 1, 3, and 5) and an unsealed position (FIGS. 2, 4, and 5) different from the sealed position. The movable portion 32 of the mullion 30, 130, 230 may be disposed in front of at least a portion of the one or more shelves 20 when in at least the sealed position. More specifically, the movable portion 32 may be disposed between the one or more shelves 20 and the French doors 12 when in the closed position. Further, in the embodiment shown in FIGS. 3 and 4, the movable portion 32 may remain disposed in front of the one or more shelves 20 in the unsealed position. In the embodiments shown in FIGS. 2 and 5, the movable portion 32 of the mullion 30, 230 may be disposed out from in front of the one or more shelves 20 when in the open position. When in the sealed position, the sealing surface 31 of the combined fixed portion 34 and the movable portion 32 of the mullion 30, 130, 230 sealingly engages the one or more of the French doors 12. The one or more movable portions 32 may be moved from the sealed position towards the unsealed position in a variety of ways and paths such as but not limited to pivoted (e.g. up, down, and/or side), translated (e.g. up, down, left, right, and/or inwardly/outwardly), and/or rotated. It should be understood that the mullion 30, 130, 230 and portions thereof may be a variety of constructions, materials, sizes, shapes, quantities, and orientations. The mullion, fixed portion, and/or movable portion may be a variety of materials and constructions. For example, the mullion may be made of plastic, stamped and/or painted metal (e.g. magnetic sealing surface). Moreover, for example, the sealing surface may include a metal surface. In some embodiments, the mullion or portions thereof may be entirely of metal. Moreover, one or more DC heaters (not shown) may be used with the mullion in some embodiments. The mullion, or portions thereof, may be heated. For example, contacts or a harness may be used to power the heater, if used, when the shelf 20 is in the closed position and/or the movable portion 32 is in the sealed position. Further, foam may be used to provide adequate insulation values. In the embodiments shown in at least FIGS. 1-4, the movable portion 32 may be vertically aligned with and/or above the fixed portion 34. The fixed portion 34 extends only partially or for a distance between the lower case and upper case of the housing 14 defining the freezer compartment 13. The movable portion 32 and/or fixed portion 34 may be a variety of positions/orientations relative to each other. For example as shown in FIG. 5, the movable portion 32 is vertically aligned with a lower portion 35 of the fixed portion 34, with the fixed portion 34 extending from the upper case to the lower case of the frame. Further, for example, one embodiment of the mullion may include one or more movable portions vertically positioned between an upper fixed portion and a lower fixed portion of the mullion. As shown in the Figures, the fixed portion 34 or partition of the mullion may be adapted to accommodate one or more shelves or compartment bins to retract and/or deploy from the freezer compartment 13 (e.g. through openings 13 b and/or 13 c). As such, the fixed portion 34 and the respective lateral side of the freezer compartment may include a sliding mechanism, rail, or the like for one or more shelves.

Although embodiments of the mullion are shown in the figures, it should be understood that the mullion, fixed portion, and/or movable portion may be of a variety of shapes, sizes, quantities, orientations, and constructions and still be within the scope of the invention. For example although a substantially vertical mullion is shown in the embodiments, a horizontal mullion or other combination of orientations/positions may include one or more fixed portions and/or movable portions to define compartments.

A variety of bin compartments, containers, baskets, or shelves 20 may be received within the freezer compartment 13 for receipt and storage of food items. The one or more shelves 20 may move between a closed position (FIG. 1) and an open position (FIG. 2). The one or more shelves 20 may be disposed within the freezer compartment 13 when in the closed position and at least partially disposed outside the freezer compartment 13 when in the open position. In some embodiments, the one or more shelves 20 may be disposed outside the freezer compartment 13 in the open position when each of the French doors 12 are in the open position. Alternatively stated, the shelf 20 may not be able to extend to the open position when a single French door 12 is closed. The one or more shelves 20 may be slidably mounted within the freezer compartment 13. In this regards, the shelf may include slides or rails that are mounted on opposing sides of the shelf 20. It should be understood that other mechanisms may be used to retract and/or deploy the one or more shelves relative to the freezer compartment 13. Additionally, in some embodiments, the one or more shelves may be powered to extend/retract automatically when one or both French doors are opened/closed.

The one or more shelves 20 may be a variety of shapes, sizes, constructions, quantities, and positions with the freezer compartment 13. For example, in the embodiments shown in FIGS. 1-4, the one or more freezer shelves 20 may have a width larger than a width of the opening 13 b, 13 c of the freezer compartment 13 or covered by at least one door 12 when the door is in the closed position. As a result, the one or more shelves may substantially extend the entire width of the freezer compartment 13. The movable portion 32, when in at least the sealed position, is disposed in front of the shelf 20 and is subsequently displaced to the unsealed position to allow the one or more shelves to pass through a larger area of the opening 13 a of the freezer compartment 13 previously interrupted by the movable portion 32 of the mullion 30, 130, 230. In some embodiments, the one or more shelves 20 may have a width less than the width of the freezer compartment 13. In the embodiment shown in FIG. 5 the shelf 20 may not extend the entire width of the freezer compartment 13, however, the shelf 20 overlaps the lower fixed portion 35 and may be wider than the opening through a door 12. Further, as shown in FIG. 5, the fixed portion 34 may extend from the top wall to the bottom wall of the freezer compartment. The fixed portion 34 is stepped to the side creating a ledge 38 for the at least one shelf 20. The ledge 38 may be substantially horizontal portion of the fixed portion 34 extending from the opening 13 a towards the rear of the freezer compartment 13. The movable portion 32, when in at least the sealed position (e.g. shown in solid lines), is disposed in front of the shelf 20, adjacent the ledge 38, above the lower fixed portion 35 of the fixed portion 34 to create the sealing surface. The movable portion 32 pivots about the pivot axis 37 in relation to the upper fixed portion 39 of the mullion fixed portion 34 when the shelf 20 is deployed from the closed position to the open position.

In use, the position of the one or more freezer shelves 20 may correspondingly adjust the movable portion's 32 position relative to the fixed portion 34 of the mullion 30, 130, 230. The position of one or more freezer shelves 20 into and/or out of the freezer compartment may adjust the movable portion 32 between the sealed and unsealed position. In the embodiments shown, when the one or more freezer shelves 20 are in the closed position, the movable portion 32 may be in the sealed position. In the sealed position, the pair of freezer doors 12 may sealingly engage the sealing surface 31 of the combined fixed portion 34 and the movable portion 32 of the mullion 30, 130, 230. Moreover, when the one or more shelves 20 are in the open position the movable portion 32 may be in the unsealed position. One or more shelves may operate one or more movable portions of the mullion. In some embodiments (e.g. FIGS. 3-5), one shelf 20 may adjust one movable portion 32 of the mullion 130, 230. In other embodiments, two shelves 20, an upper shelf 22 and/or a lower shelf 24 (e.g. separately or together), may each reconfigure one movable portion 32 of the mullion 30 (FIGS. 1 and 2). In addition, in some embodiments, one shelf may reposition one movable portion and another shelf may reposition another movable portion. It should be understood that a variety of mechanisms, devices, and/or other portions of the appliance, alone or in combination with the one or more shelves, may adjust the movable portion of the mullion between the sealed and unsealed positions.

As shown in the Figures, the movement of the movable portion 32 may coincide with the movement of the one or more movable shelves 20 and/or may allow the shelves to pass through a larger area of the opening 13 a of the freezer compartment 13 previously interrupted by the movable portion 32 of the mullion 30, 130, 230. In some embodiments, the movable portion 32 is disposed in front of the one or more shelves 20 in the sealed position, when the doors may be in closed position and/or the open position. The movable portion 32 of the mullion 30, 130, 230 may be displaced or repositioned between the sealed position and the unsealed positions. In some embodiments as shown in FIGS. 1, 2, and 5, the one or more freezer shelves 20 may pivot the movable portion 32 of the mullion 30, 230 at least from the sealed position towards the one or more unsealed positions. The movable portion 32 may pivot about a hinge 36 between the sealed position and the unsealed position. As shown in FIGS. 1 and 2, the movable portion 32 of the mullion 30 pivots about a hinge 36 having a pivot axis 37 being in a substantially horizontal orientation/plane. Although the hinge 36 connects the fixed portion 34 to the movable portion 32, the hinge 36 and/or movable portion 32 may be a variety of orientations, positions (e.g. sealed and/or unsealed positions), constructions, shapes, sizes, and still be within the scope of the invention. For example, the hinge 36 of the movable portion 32 may be in a substantially vertical orientation/plane as shown in FIG. 5. Moreover, as shown in FIG. 5, the movable portion 32 swings or pivots to the side instead of upwards and/or downwards (FIG. 2). In some embodiments, one or more movable portions 32 may be hingedly attached to the housing 14 (e.g. surrounding the opening 13 a) instead of or in combination with being attached to the fixed portion 34 of the mullion as shown.

The movable portion 32 may be positioned from the unsealed position to the sealed position and/or from the sealed position to the unsealed position in a variety of ways and constructions. In the embodiments shown in FIGS. 1, 2, and 5, the movable portion 32 may include one or more torsional springs (not shown). Once the shelf is closed or retracted, the movable portion 32 may be under spring torsion and is urged to return to the sealed position or disposed back in front of the one or more shelves to create the sealing surface for the pair of freezer doors. If a spring is used in some embodiments, a damper may be included. In some embodiments, a user may need to return the movable portion 32.

The movable portion of the mullion may be moved or repositioned in a variety of ways between the sealed position and the unsealed position, not limited to pivoting shown in FIGS. 1, 2, and 5. In some embodiments, the mullion may translate (e.g. linear direction) between the sealed position and the unsealed position. As shown in FIGS. 3 and 4, the movable portion 32 of the mullion 130 translates with the one or more shelves 20. The movable portion 32 may be fixedly attached to the one or more freezer shelves 20. The shelf 20 may include a front side 26 adjacent the opening 13 a of the freezer compartment 13 and an opposing back side. The movable portion 32 of the mullion 130, attached to the font side 26 of the shelf, is positionable between the closed position (FIG. 3) and the open position (FIG. 4) with the freezer shelf 20. The movable portion 32 may travel or be carried with the one or more freezer shelves 20 from the closed position (FIG. 3) to the open position (FIG. 4). The movable portion 32 of the mullion 130 is attached to the front side 26 of the shelf 20 (e.g. disposed in front of the shelf 20) and is in the sealed position with the fixed portion 34 of the mullion 130 when the shelf 20 is in the closed position. When the shelf 20 is in the open position, the movable portion 32 is in the unsealed position, and may also be described as being disposed in front of the shelf in some embodiments. Further, the movable portion 32 returns to the sealed position (FIG. 3) with the shelf when the shelf 20 retracted to the closed position. In some embodiments, if a heater is used, an electrical connection may be restored when the movable portion 32 returns to the sealed position.

While several embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, embodiments may be practiced otherwise than as specifically described and claimed. Embodiments of the present disclosure are directed to each individual feature, system, article, material, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, and/or methods, if such features, systems, articles, materials, and/or methods are not mutually inconsistent, is included within the scope of the present disclosure.

All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.

The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.”

The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.

As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited.
